GYRATING SIEVE OR BOLTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 720,559, dated February 17, 1903. Application filed November 8, 1901. Serial No. 81,611. (No model.)

To all whom it may concern: Y

Be it known that I, DANIEL E. BURNER, a citizen of the UnitedStates, residing at Ho poor, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Gryrating Sieves or Bolting- Machines; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement in gyratingsieves or bolting-machines; andits objects are to prevent one end or side of the sieve box moving farther or faster than another part thereofor, in other words, to prevent unequal or irregular movements of the sievebox or of parts thereof; to allow the sieve-box perfect freedom of orbital movement by and with the driving-crank, restraining its movement only by the crank, and to insure that every part of the sieve-box shall describe or move in the same circle, be held exactlyin po.- sition, and have an equal and exact motion.

To these ends the invention consists in the novel means of supporting or suspending the sieve boxes or bodies of bolters, gyrators, "and other sifting-machines (such as are com monly used in fiouring-millsand sifting processes generally) adjacent to a single driving-crank preferably arranged horizontally below and centrally of the sieve-box, the said means embodying four vertical jointed members,which are so connected together as to perform the functions of a universal support or suspension for the sieve-box, but which are compolled by their novel arrangement and connection to move uniformly and exactly alike, so that if one of such members be shifted in any direction all the others are compelled to correspondingly and simultaneously shift, with the result that all parts of the sieve-box are kept precisely in line and all parts thereof moved synchronously, if at all.

In my invention the motion of the sieve-box is perfectly regular throughout its entire orbital movement, Which corresponds with that described by the crank or driving pin, so that any natural pitch or fall allowed to the sieves in the original adjustment of the sieve-box is fully utilized and constantly maintained and the stock will and must travel in the desired direction during the operation of the machine. The invention will be clearly understood from the following description in connection with the accompanying drawings, and I refer to the claims for concise summaries of the features upon which protection is desired.

In said'drawings, Figure 1 represents a side elevation of a gyratory sieve or bolting-machine embodying my invention. In this case the sieve-box is shown suspended. Fig. 2 is a similar view showing the sieve-box supported. Fig. 3 is a View of the jointed members constituting the principal portion of the invention detached from the sieve-box. In this view a d-iiferent or modified form of bingejoint for the members is shown. Figs. 4 and 5 are enlarged side and sectional views of such modified form of joint. Figs. 6 and 7 are face and edge views of the preferred form of joint or coupling device employed in the invention.

Fig. 8 is a section through such joint on line 8 8, Fig. 7.

The presentinvention is equally well adapted for holdingthe sieve-box in position either by suspending it from the ceiling or overhead supports or for supporting it from the floor, the operation and construction of the jointed members being unchanged in either situation and their use in either manner being merely a matter of choice or selection by the erector or mill-owner. The apparatus embodying the invention (see Figs. 1, 2, and 3) comprises, briefly, two transverse parallel members A A, four vertical parallel members B B, and two longitudinal parallel members 0 O, which are connected together by swinging or hinge joints, as hereinafter described. All the members are preferably made of tubing for purposes of lightness and strength, but may be solid and of any desired cross-section.

The members A A are arranged underneath and transversely of the sieve box or body S, which may be of any desired kind, said-members A being journaled in boxes 3, attached to the sieve-body, as shown, so as to permit the said members to rock. To each end of each transverse member A is attached one end of a vertical member B by means of a joint so constructed as to permit the members B to swing longitudinally of members A or transversely of the sieve-box S. The other ends of the vertical members B are connected by similar joints to the ends of the parallel horizontal members C. The members 13 at the same end of the machine are connected to members A, while adjoining members B at the same side of the machine are connected to members C. The joints connecting members B and C are, however, set at right angles to the joints connecting members A and B, so that members 13 can swing longitudinally of members 0, and thereby longitudinally of sieve-box S. The members C are kept in parallelism, being journaled at their ends in boxes 0 c, which may either be suspended from adjustable hangers 0, attached to the ceiling, as indicated in Fig. l, or may be attached directly to the base or support beneath the sieve-box, as indicated in Figs. 2 and 3. In the latter case it is convenient to attach the boxes 0 to horizontally-disposed side beams 0 between which may be secured the pedestal H, in which is journaled a stubshaft carrying the crank or fly wheel I and belt-pulley 2', (shown in Figs. 1 and 2,) said wheel I having a crank-pin I engaging a yoke or boxing S, attached to the under side of the sieve-box, so that the location of the crank-wheel imparts a gyratory motion to the sieve-box in the well-known manner.

It will be noted first that by reason of the peculiar joints between the vertical members B and the opposite members A and O the sieve-box can move in any direction or gyrate; but the members A B C are so connected that one member B cannot swing in any d irection without imparting or causing an exactly similar simultaneous movement of everyother member B, because the connecting members A and O and the sieve-box itself transmit motion of one member B synchronously to every other member. The members A being journaled in bearings rigidly attached to the sieve-box, the latter forms a bond between the members A A and holds them accurately and positively in alinement. If one member A is moved, the other is necessarily correspondingly moved by its connection with the sievebox. If one member 0 is rocked, the other is necessarily similarly rocked by reason of the connecting members B A. This peculiar connection between the members, whereby the four vertical members 13 B are caused to positively move synchronously, insures the most perfect operation of the machine and is notably different from the ordinary arrangements heretofore employed, Where four independent vertical suspending or supporting members have been used, the only connection therebetween being the sieve-box itself, such independence of the members permitting irregular motions of the sieve-box, which materially impair the effectiveness of the old machines, whereas owing to the positive compelling connections between the four vertical members in my machine such irregular movements are entirely prevented.

The joints between the members A B and B O are preferably of the kind indicated in Figs. 1 and 2 and shown clearly detached in Figs. 6, '7, and 8. Each of said joints consists of a socket-piece D, having bifurcations d, transfixed by a hinge-bolt E, on which is hung acasting E, having a socket e and lug e at right angles to socket 6, lug a being transfixed by bolt E, which thus secures parts D E together, with sockets D e at right angles to each other and capable of swinging only in one plane toward or from the other. As shown in Figs. 1 and 2, the parts D are rigidly fastened to the extremities of the vertical members 13, preferably by tapered pins or through-bolts, (indicated at d,) while parts E are similarly rigidly attached to the extremities of the transverse and longitudinal members A and C, as shown. It Will be noted that parts D are attached to members A, so as to stand at right angles to each other, (see Figs. 1 and 2,) so that the hinge-joints at opposite ends of said members B will only op erate at right angles to each other.

In some instances the form of joint shown in Figs. 3, 4, and 5 may be preferred. These joints are composed of two disks Ff, fitted closely together and secured by a through center-bolt F Disk F is provided with a socket F at right angles to bolt F and disk f is provided with a socketf, perpendicular to bolt F and at right angles to socket F. As shown in Fig. 3, the disks fare rigidly secured to opposite ends of the vertical members B, while disks F are rigidly secured to the members A and O. The disksf on opposite ends of members B are, however, set at right angles to each other, so that the proper relation of the series of hinge-joints is maintained.

It will be observed that the principle or function of my apparatus is exactly the same whether it be employed to suspend or support the sieve-box or whether disk or fork joints or other suitable controlling-joints are employed to connect the members. Its opera-. tion may be briefly described as follows: Should one supporting or hanging memberB move in any direction, by reason of the controlling connections every other member Bis caused to move exactly and synchronously therewith, and the sieve-box, although given a like movement, is prevented from twisting or turning on its own center or axis. The hinge-joints transmit motion from one memher to another, so that all members move in conformity to the motionof the driving pin or crank, and at the same time the vertical members are kept from any independent play or motion, and every part of the sieve-box moves in exact unison with the central part or drive and relieves said box of all tendency to become irregular or wild in its motion or for one end thereof to have less motion than the other.

duced to a minimum, resulting in saving of,

power. All parts are readily accessible and the operation of the machine noiseless, and a perfect gyratory motion is imparted to the sieve-box.

The apparatus is applicable to all kinds and sizes of sieve-boxes, no framework is required, and the height of the sieve-box can be readily regulated by properly proportioning the length of the vertical members.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
